Rapid Shutdown has traditionally meant putting module level power electronics in the array for PV systems on buildings. There has always been this part of the NEC 690.12(B)(2)(1) that gave you an option to comply with rapid shutdown inside the array with a listed hazard control system. Surprisingly, we can now go back to having something to what rapid shutdown used to be in the 2014 NEC, which we called array level rapid shutdown.
